create a wordpress plugin from another already made plugin

Ai power chatbot plugin that has multiple features of connecting to various external APIs such as openai, google or pinecone, but it brings additional features that are not necessary for me, such as posting with ai or generating images, I do not need these features, only those corresponding to the chatbot, ai and connections to api. I need a similar plugin to be created from this plugin with some additional features for the AI ​​chatbot.
